Sls – Safely-Limited Speed - Festo CAMC-G-S3 Manual

2 Product description of safety module CAMC-G-S3
2.5.8 SLS – Safely-Limited Speed
The function described here implements the safety function SLS according to EN
61800-5-2.
Use the "Safely-Limited Speed" (SLS) function when, in your application, you wish to
prevent the motor from exceeding a specified speed limit.
The function is indicated by a zero-symmetrical monitoring area for the speed. The limits
can be set separately.
The drive can be braked to an approved speed along the slowdown ramp, although the
function can be switched off. In the simplest case, monitoring starts after the time "Time
delay until monitoring starts" (P0E.01/P0E.15/P0E.29/P0E.3D). The maximum rotational
speed is specified using "Safe speed - upper limit" (P0E.07/P0E.1B/P0E.2F/P0E.43).
The following parameterisation means that the Safe Speed Function SSF corresponds to the SLS safety
function (with immediate speed monitoring without slowdown ramp):
